Product details
Overview
R5F72145HDFP#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A CPU core, featuring 512 KB on-chip Flash memory, 64 KB RAM, and integrated peripherals including USB 2.0 FS host/device controller, CAN controller, 12-bit ADC (16 channels), and multiple serial interfaces (SCI, I²C, SPI). It targets industrial control and embedded automation systems requiring deterministic real-time response and mixed-signal integration.
For engineers reviewing the R5F72145HDFP#V1 datasheet, R5F72145HDFP#V1 pinout, R5F72145HDFP#V1 application, or R5F72145HDFP#V1 equivalent, key selection criteria include its SH-2A core performance (up to 120 MHz), USB + CAN dual-protocol support, 12-bit ADC resolution with sample-and-hold, and QFP-144 package compatibility for space-constrained industrial HMI and motor control designs.
Technical Context
The R5F72145HDFP#V1 implements the SH-2A superscalar RISC architecture with dual-issue capability, supporting both integer and floating-point operations via integrated FPU. Its system clock is derived from an on-chip PLL with selectable input sources (crystal, ceramic resonator, or external clock), enabling precise frequency control for USB 48 MHz and peripheral bus timing.
Peripheral integration includes a Data Transfer Controller (DTC) for zero-CPU-overhead data movement, an Interrupt Controller (INTC) with 128 vectors and priority levels, and a Clock Pulse Generator (CPG) supporting dynamic mode switching between high-speed, low-power, and stop modes - all coordinated through dedicated system control registers accessible in privileged mode.

FAQ
What is the maximum operating frequency of the R5F72145HDFP#V1?
The R5F72145HDFP#V1 operates at a maximum CPU frequency of 120 MHz, achieved using the on-chip PLL with an external crystal (4–20 MHz) or ceramic resonator. This frequency applies to the SH-2A core and synchronized peripheral clocks, subject to voltage (3.0–3.6 V) and temperature (−40 °C to +85 °C) compliance per the Hardware User's Manual Rev. 4.00.
Does the R5F72145HDFP#V1 support USB device and host modes simultaneously?
No, the R5F72145HDFP#V1 integrates a single USB 2.0 Full-Speed controller that operates in either device mode or host mode - not both concurrently. Mode selection is configured at initialization via the USBPHYCTL register; switching requires reinitialization and is not runtime-dynamic. The R5F72145HDFP#V1 does not implement OTG functionality.
Is the R5F72145HDFP#V1 pin-compatible with other SH7214 Group members?
Yes, the R5F72145HDFP#V1 shares identical pin assignment and electrical characteristics with other 144-pin LQFP variants in the SH7214 Group (e.g., R5F72144HDFP#V1, R5F72146HDFP#V1), enabling drop-in replacement within the same memory/peripheral configuration constraints. Pin compatibility is confirmed in Section 1.3 of the SH7214 Group Hardware User's Manual.
What debug interface does the R5F72145HDFP#V1 provide?
The R5F72145HDFP#V1 features a FULL-EMI debug interface compliant with IEEE 1149.1 JTAG, supporting real-time instruction trace, hardware breakpoints, watchpoints, and memory access during active execution. Debug access requires the Renesas E2 emulator or compatible JTAG probe; no SWD or cJTAG interface is implemented on the R5F72145HDFP#V1.
Does the R5F72145HDFP#V1 include error-correcting code (ECC) for Flash memory?
Yes, the R5F72145HDFP#V1 implements single-bit error correction and double-bit error detection (SEC-DED) across its entire 512 KB on-chip Flash memory array. ECC logic operates transparently during read/write/erase cycles and is enabled by default after reset; disabling ECC is not supported. This enhances reliability in industrial environments subject to radiation-induced soft errors.
